Privacy Policy
Identities of users of this Site are not anonymous, but names of users and personal
identifying information about users will not be provided to any third parties.
For the purposes of collecting, analyzing, and reporting data in the context
of this research study, all users will be identified by a unique identifier,
not by name, and this information will not be treated as confidential. Information
about users may be provided to third parties, but will be done so without identifying

Columbia University does use IP addresses, domain information and other access
statistics to analyze trends, administer the Site, track users' movements, and
gather broad demographic information for aggregate use. This information is
not linked to personally identifiable information. Columbia University may share
aggregated demographic information with third parties. Aggregate information
is not linked to any personal information that can identify any individual person.

This Privacy Policy applies to your use of the Site. This Privacy Policy does
not apply to your use of any other sites operated by Columbia University or
affiliated or unaffiliated third-party sites to which the Site may link.

Exceptions
In certain circumstances, and as exceptions to this Privacy Policy, we will,
without notice to you, release specific information about you or your account
to comply with any valid legal process such as a search warrant, subpoena, statute
or court order, or in other special cases, such as, for example, an attempted
breach of the security of the Site, or a physical threat to you or others.

We may change this Privacy Policy from time to time to address new issues and
reflect changes on this site, and as the need arises. All changes to this Privacy
Policy will be posted here. Please refer to this Privacy Policy regularly. If
you have any questions or concerns about this Privacy Policy, please send us
